  • Description


    JW®3633 is power management solution for portable battery charger system.

    The device contains a full-featured battery charger with up to 2A charge current, a 2.4A output and battery protection functions.

    Charge mode: The charger can be powered from 5V wall adaptor with ±10% variation whereas over voltage lock out protects internal circuit during voltage surge.

    The device automatically turns-off charging and bypassing function when input voltage exceeds 6.1V, and can sustain up to 10V continuous input voltage with charging and bypassing function in OFF status.

    The device has a preset battery float voltage of 4.2V/4.35V programmable by external resistor with ±1% accuracy at room temperature. The integrated charger minimizes the charger’s physical footprint, maximizes charge efficiency, which reduces the power dissipation during charge.
